A Facility for Transient Testing of Mobile Air Conditioning Systems
No full textA majority of the design and component selection processes for mobile air
conditioning systems are based on results obtained from steady-state analyses.
Although valuable, these steady-state tests do not accurately simulate the
operation of mobile air conditioners. To allow transient testing of mobile air
conditioning systems for use in model development and component selection, a
heavily instrumented test facility was built. The test facility can accept any
prototype or production mobile air conditioning systems. The curre.n t setup
contains up-to-date components from a Ford 1994 Crown Victoria R-134a air
conditioning. system. The design and construction of the Crown Victoria test
sections, as well as several improvements made to the test facility, are discussed in
detail.
The test facility can achieve condenser and evaporator air-side versus
refrigerant-side energy balances within 5% - quite good considering the large
range of operating conditions tested. Also included in this report is a collection of
preliminary transient results. These results display the versatility of the test stand
and the ability to collect quality transient data. Future reports from this project will
contain additional transient results and analyses.Submitted by Megan Hayes ([email protected]) on 2009-04-17T19:26:21Z

R32 Compressor for Air conditioning and Refrigeration applications in China
Get PDFThis paper evaluates the compressor performance and reliability impact by using R32 refrigerant for air conditioning (residential and commercial system); Performance and reliability impacts are compared with different popular refrigerants used in China, for example, R410A & R22 for AC. The design improvement on the scroll compressor will be discussed in order to reach required efficiency and reliability; these improvements include lubrication, internal heat management, motor design, and vapor injection technologies, etc
New Energy-Efficient Electromagnetic Clutch for Automotive Air Conditioning Compressors
Get PDFEven if the air conditioning is switched off, the internal combustion engine in today’s cars continues to drive the common compressor. To avoid resulting power losses, the automotive industry aspires to apply electromagnetic clutches. When the air conditioning is used, however, CO2-emission increases significantly because the electromag-netic coil consumes electricity. The CO2-reduction per year is consequently very low, which is why new compressor clutches were developed that do not require a permanent electric power supply. Additionally, these clutches are characterized by low production costs, a simple functional principle and a small package
Geothermal- And Solar Assisted Air Conditioning System
Get PDFA research project of the Hamburg University of Technology realizes an open cycle desiccant assisted air conditioning system based on renewable heat sources e.g. solar thermal and heat sinks e.g. shallow geothermal energy. Both advantages of the open cycle process are taken into account, the possible use of a heat sink at higher temperatures and the use of low calorific heat. Moreover, the total system combines additional aspects of an energy efficient air conditioning system e.g. ventilation fan control, a bypass system to reduce extra pressure losses and space heating / cooling. All pumps of the system are frequency controlled and belong to the group of energy-saving pumps. The geothermal system comprises 3 boreholes with a depth of 75 m (246ft) and 5 energy piles with a depth of 14 m (46ft) and supplies the cooling energy for the air conditioning system. A solar thermal system with 20 m² flat panels supplies the low calorific heat. By using space heating e.g. floor heating and the space cooling e.g. floor cooling, cooling beams even more energy can be saved by the separation of cooling and ventilation due to the higher heat capacity of water. This paper presents the results of the demonstration plant for the years 2009 and 2010. The influences of several aspects of an energy efficient air conditioning system combined with a demand oriented control system are presented as well as experiences in dynamic modeling
